And back here at home, we're learning more this evening about that jet turned around over west Virginia, escorted back to the Toronto airport with U.S. Fighter jets at its side. And here was the scene when it landed. Heads down, hands up! Heads down, hands up! On board, they were searching for a man who terrified fellow passengers. Well tonight, the stories now emerging from inside the plane. The other passengers now talking. And there was yet another emergency lands once that plane got back intthe air. This time, it was something else. ABC's Linzie Janis tonight. Heads down, hands up! Reporter: A Canadian S.W.A.T. Team storming a commercial flight, as armed officers zero in on a man suspected of making a bomb threat. Heads down, arms up, yelling. The kids were scared. Reporter: Less than an hour earlier, U.S. Authorities scrambling two fighter jets to escort the sunwing airlines flight back to Toronto. Going to land runway 33 left and they have a bomb threat. You might see a pair of F-16s. Reporter: The plane, with 181 passengers on board, en route to Panama Friday morning, turning around over West Virginia, after police say 25-year-old Ali shahi started making direct threats to the aircraft. Once he started yelling things about the plane crashing and everyone dying, of course, people were a little taken aback by it. West Virginia is getting a little close to Washington, D.C., and we're very, very paranoid about any untoward activity in the air near Washington, D.C. Reporter: But this heart-stopping footage now raising questions about the intensity of the reaction. The fact is, if somebody had a bomb and they had their finger on the trigger and these guys come aboard yelling, that probably would have been the end of the matter right there, it would have been detonated. So, I'm not sure this was the correct reaction. Reporter: The flight finally reaching Panama after being diverted yet again Friday night, this time to Jamaica, after another passenger fell ill. Tonight, shahi, believed to suffer from mental illness, is out on bail after being charged with endangering an aircraft. Linzie Janis, ABC news, new York.
